Small, Single-/Multi-Cell Solar Harvester with
MAX20361
MPPT and Harvest Counter
General Description
Benefits and Features
The MAX20361 is a fully integrated solution for
harvesting energy from single-/multi-cell solar sources.
The device includes an ultra-low quiescent current
(360nA) boost converter that is capable of starting from
input voltages as low as 225mV (typ). In order to
maximize the power extracted from the source, the
MAX20361 implements a proprietary maximum power
point tracking (MPPT) technique that allows efficient
harvesting from 15μW to over 300mW of available input
power.

The MAX20361 also features an integrated charging
and protection circuit that is optimized for Li-ion
batteries, but can also be used to charge
supercapacitors, thin-film batteries, or traditional
capacitors. The charger features a programmable
